Abstract
Organised Molecular Systems have been used to control the synthesis of calcium phosphate, through to the role of surfactant molecules at the mineral-organic interface. The influence of various parameters on the nature of the solid obtained has been examined: nature of the oil, type of surfactant, (Ca/P)r atomic ratio in the reactants, and also ageing. This method of synthesis allows the size and the morphology to be controlled and nanometric crystals to be obtained.
